This one perfect Snapchat hack corrects the app's most annoying problem

To view a picture or video in the social media app, one finger must be kept on the phone screen at all times. Where you place that finger is the key. If you put your finger on the wrong section of the screen, you might miss something important.

The one-finger rule is supposed to protect images from being screenshotted, though it's totally easy to get around that. Snapchat is reportedly considering doing away with the finger requirement entirely.
